Like the other units of the Triarii Protectorsbrigade the Tenth became more active as open warfare erupted across the Inner Sphere. The Tenth were stationed on New Earth in February 3145 when an abandoned facility near Meredith that had belonged to the Word of Blake was raided by an unknown force. Units from the Tenth moved to intercept the raiders, but the attackers vanished shortly before the interceptors arrived at the site. Those first responders from the Tenth who had moved to intercept the invaders were removed from the Tenth and transported to Mars for debriefing by the Department of Military Intelligence, who also cordoned off the entire of the former Blakist facility. Several months later the missing personnel from the Tenth still hadn't been returned to the unit, and official inquiries into their return were rebuffed by the Republic High Command. Uncomfortable with the situation, the commanding officer of the Tenth, ColonelDmitry Bykov, finally requested replacement personnel by November the same year.[4]
